VBR v12.1 – Malware Detection Methods

In this blog, I’ll be exploring the new security features that are included in the latest version of Veeam Backup & Replication v12.1, this includes Inline Entropy Analysis, File Index Analysis, and YARA Scanning.

Veeam Backup & Replication v12.1 – Malware Detection

Inline Entropy Analysis
Analyses each source disk block on the fly using an AI/ML-trained model. The scan occurs during every backup run, providing real-time insights into potential anomalies or threats at the block level. Veeam looks for ransomware notes, onion links and data that has recently become encrypted without needing additional software.

Inline analysis is disabled by default, given it’s potential resource consumption so when planning to enable this feature be sure to check if your backup proxies have spare CPU resources, plan for 10-15% additional CPU load per proxy. After enabling, during the first backup run, a full disk scan is performed to create a baseline (not a full backup). It’s possible to exclude machines to reduce the impact during this intial scan using Malware Exclusions.

The sensitivity for inline entropy analysis can be adjusted, it’s recommended to use low sensitivity for environments with heavy encryption usage.

Let’s dive deeper and have a look at a how Veeam inline entropy scanning works once it’s enabled,

Pay the ransom and hope for the best…

Ransomware isn’t sexy but it’s certainly an important topic in today’s IT security landscape, with unprecedented growth and relentless evolution, organisations need to constantly keep one step ahead of bad actors eager to make a buck by exfiltrating and encrypting your important data.

Ransomware attacks mainly occur because IT is a complex and everchanging environment, organisations are busy modernising their applications from monolithic designs to new highly distributed container-based services. The remote workforce is now connected more than ever, with the ability to access data hosted across multiple cloud providers, connecting from virtually any device, at any hour of the day. IT departments are being asked to do more with less each and every year while ransomware attacks are on the rise and becoming more costly than ever before.

If you’re questioning whether or not your organisation could be targeted by ransomware, it’s a question of when not if

Beyond encryption of data, some ransomware is taking it a step further and making ransom of leaking data, this is otherwise known as data exfiltration. Unfortunately, stopping ransomware prior to an attack is difficult and at best, inconsistent. No single product or service has all the solutions to the challenges raised by these attacks, instead, it’s recommended to take a multi-layered approach. Apply best practices, keep systems up to date, enforce good data hygiene, configure event logging, and identify anomalies (indicators of compromise) to provide the best chance of discovering an attack as early as possible.
